CREAM COOLER AND AER ATOR.

Specification of Letters Patent.

Patented Jan. 2, 1906.

Application filed March 14,1904. Serial No. 198,157.

To all whom it may concern:

Be it known that I, MARTIN MORTENSEN,

a citizen of the United States, residing atv aerators.

vice.

The object of theinvention is to provide a device of the class referred to for cooling and aerating cream as it comes from the separator.

The invention further aims to provide a cream cooler and aerator which shall be extremely simple in its construction, strong, durable, efficient in its use, and comparatively inexpensive to manufacture.

With the foregoing and other objects in view the invention consists of the novel combination and arrangement of parts hereinafter more specifically described, illustrated in the accompanying drawings, and particularly pointed out in the claims hereunto appended.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, wherein like reference characters denote corresponding parts throughout the several views, and in which Figure l'is a perspective view of the de- Fig. 2 is a plan view with the bottom of the cream-compartment removed, and Fig. 3 is a longitudinal sectional view of the device.

Referring to the drawings by reference characters, the device consists of a substantially rectangular receptacle divided into two compartments, one of which may be termed the compartment for the cream and the other the compartment for the cooling medium.

The receptacle is constructed with a bottom 1, a pair of side walls 2 3, a rear end wall 4, and a forward end wall 5. The end wall 5 is of greater hei ht than the end wall 4 and 6X1- forward end thereof, and by such construction the forward end of each of the side walls 2 3 is enlarged. The function of the enlarged end of the side walls and the constructing of the end wall 5 of greater height than the end wall 4 and also at an inclination will be hereinafter referred to.

' Within the receptacle 1 is suitably secured a partition 7, so as to form the said receptacle into a compartment for the cream and a compartment for the cooling medium. The partition 7 forms the bottom of the compartment for the cream and the top of the compartment for the coolingmedium. The bottom 1 of the receptacle forms the bottom of the compartment for the cooling medium, and within said compartment is secured a series of deflectors 8, arranged in a staggered manner,

so as to form a serpentine channel for the cooling medium, which preferably is water, and to furthermore cause the cooling medium to circulate throughout the compartment therefor.

Connected to the side wall 2 at its forward end is an outlet-pipe 9 for the cooling liquid, and secured to the bottom 1 at its lower end is an inlet-pipe 10 for the cooling medium.

The partition 7 at its rear end is formed vwith a transversely-extending collectingtrough 11, communicating with a dischargespout 12 for the cream. The spout 12 projects away from the receptacle 1 and is suitably secured to the side wall 2 at the rear thereof, the latter being cut away to permit of the discharge of the cream from the trough 11 into the spout 12.

At the forward end of and within the receptacle 1 is secured an inclined plate 13, having a plurality of filtering-openings 14 near the lower edge thereof. The plate 13, in connection with the enlarged ends of the side walls 2 3 and also in connection with the end wall 5, forms a V-shaped trough 15 to receive the cream as it leaves the separator. The V-shaped trough with the filtering-openings, as before stated, is adapted to receive the cream from the separator, and as the cream leaves the trough 15 it is filtered and passes onto and over the upper surface of the partition 7 in a thin sheet and collected in the trough 11, thence discharged from the receptacle through the medium of the discharge spout 12. It is desirable to cause the cream to flow in a thin sheet for two reasons: first, it will more readily expel the dissolved gases which fresh cream contains, and thereby improve the flavor of the cream, and, second, the cream is cooled to a temperature at which the fermentation present in it develops very slowly. This helps to prevent the cream from souring, and, furthermore, it prevents development or multiplication of disease-producing bacteria which exists in the cream.

The operation of the device is that the cooler is placed at an inclination and in such position that the V-shaped trough 15 will receive the cream as it comes out of the separator and so that the trough 15 will be a suitable height above the rear end of the cooler, the inclination of the device depending upon the c0nditionsthat is to say, the temperature of the water, the temperature of the cream, the amount of cream, and richness of the cream. Water being supplied through the inlet 10, it will be caused to circulate upward through the cooling-compartment and will be discharged through the outlet 9. Owing to the circulation of the cooling medium through its compartment, it will cause the cream as it passes over the upper surface of the partition 7 to be cooled, and in this particular it will be observed that the water is the coldest as it enters the cooling device and the warmest as it leaves the said device. The result obtained by such procedure is that the Warmest cream meets the warmest water and the coldest cream the coldest water.

It is thought that the many advantages of a cream cooler constructed in accordance with the foregoing description, taken in connection with the accompanying drawings, can be readily understood, and it will furthermore be evident that changes, variations, and modifications can be resorted to Without departing from the spirit of my invention or sacrificing any of its advantages, and I therefore do not wish to restrict myself to the details of construction hereinbefore described, and set forth in the annexed drawings, but reserve the right to make such changes, variations, and modifications as come properly within the scope of the protection prayed.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A cream cooler and aerator consisting of a single receptacle having one of its end walls extending upwardly and outwardly at an inclination and one end of each of its side walls arranged adjacent to said inclined end wall enlarged and having the upper portion proj ecting rearwardly, a partition in said receptacle for dividing it into an upper and a lower compartment, said partition having one end formed in a semicylindrical manner to constitute a collecting-trough at the lower end of said receptacle, a filtering-plate having the lower portion thereof perforated, said plate arranged above said partition, secured to the inner face of the enlarged ends of said side walls, bearing against the inclined end wall and in connection with said inclined end wall and the enlarged ends of said side walls forming a filtering-trough, a spout communicating with said collecting-trough, a coolingmedium supply pipe communicating with said lower compartment, and a coolingmedium-exhaust pipe communicating with said lower compartment.
